Yesterday, after 10 hours of debate, the UK Parliament approved the use of UK armed forces against ISIS on the territory of Syria; the German Bundestag also debated the use of force and will vote on the involvement of Germany in the coalition operation tomorrow. I found it particularly interesting to observe how the constructive ambiguity of the Security Council’s resolution 2249 (2015), that Dapo and I extensively addressed in our previous post, was used by the MPs during their debate.
When it comes to the UK Government’s official legal position on the use of force in Syria, they have been very careful not to rely on the resolution as a separate source of authority, but as a (unanimous) reaffirmation of the legal authority they already thought they had. That position is articulated most clearly in this memorandum from the Prime Minister to Parliament’s Foreign Affairs Committee, at pp. 15-17, and the legal bases for the use of force set out there are (1) the collective self-defence of Iraq and (2) the individual self-defence of the UK against ISIS, both pursuant to Article 51 of the Charter. The resolution is used to buttress these two claims, for example with the memorandum stating that: “Resolution 2249 (2015) both condemns the ISIL’s horrendous attacks that have taken place and notes ISIL’s intent and capability to carry out further attacks. It then calls upon States to take lawful action to prevent such attacks.”
Similarly, in his statement to the House of Commons on 26 November regarding that memorandum, the Prime Minister stated that:
It is a long-standing constitutional convention that we don’t publish our formal legal advice. But the document I have published today shows in some detail the clear legal basis for military action against ISIL in Syria. It is founded on the right of self-defence as recognised in Article 51 of the UN Charter. The right of self‑defence may be exercised individually where it is necessary to the UK’s own defence… …and of course collectively in the defence of our friends and allies. Mr Speaker, the main basis of the global coalition’s actions against ISIL in Syria is the collective self-defence of Iraq. Iraq has a legitimate government, one that we support and help. There is a solid basis of evidence on which to conclude, firstly, that there is a direct link between the presence and activities of ISIL in Syria, and their ongoing attack in Iraq… ….and, secondly, that the Assad regime is unwilling and/or unable to take action necessary to prevent ISIL’s continuing attack on Iraq – or indeed attacks on us. It is also clear that ISIL’s campaign against the UK and our allies has reached the level of an ‘armed attack’ such that force may lawfully be used in self-defence to prevent further atrocities being committed by ISIL.
And this is further underscored by the unanimous adoption of UN Security Council Resolution 2249. We should be clear about what this resolution means and what it says. The whole world came together – including all 5 members of the Security Council – to agree this resolution unanimously. The resolution states that ISIL, and I quote: “constitutes a global and unprecedented threat to international peace and security.” It calls for member states, and again I quote: to take “all necessary measures” to prevent and suppress terrorist acts committed specifically by ISIL… …and crucially is says that we should, and again I quote: “eradicate the safe haven they have established over significant parts of Iraq and Syria.”
Note how despite saying that “we should be clear about what this resolution means and what it says” the Prime Minister only proceeds to quote the resolution’s language, without explaining in any way whatsover (let alone clearly so) what it means and what it says. (By the way, isn’t that just wonderful howe he did that?)
